A study was developed including low doses of gonadotropin chorionic equine (GCe), the ewes' genotype and the production value of the lambs at weaning which were the offspring of hair sheep ewes. Thirty nine multipara ewes of the genotype Pelibuey purebred and the Pelibuey x Romanov cross, were synchronized using intravaginal sponges impregnated with flurogestone acetate (FGA) for 12 d. At the eleventh day of treatment, ewes of each genotype were divided in two groups and injected with 140 or 280 immunizer units (IU) of GCe. A total of two matings corresponded to each female, with 12 h interval between each one. A completely randomized design with a 22 factorial arrangement was applied to analyze the information. None of the variables was affected (P > 0.05) by the interaction dose x genotype or by the main effect of GCe dose. The production value was 25% higher in Pelibuey ewes than in Pelibuey x Romanov. Likewise it was in 32% of ewes treated with 280 IU regarding those receiving 140 IU of GCe. It is concluded that production value of the lamb at weaning is the same in Pelibuey and Pelibuey x Romanov ewes, treated with doses of 140 or 280 IU of GCe.

Two experiments were performed, according to Latin square 4 × 4, to determine the ileal and rectal digestibility of nutrients and energy in growing Yorkshire x Landrace pigs. They were fed with variable levels (0, 10, 20 and 30 % on dry basis) of sweet potato foliage meal (Ipomoea batatas (L.) Lam). In experiment 1, four castrated males, of 35 kg and prepared with an ileo-rectal anastomosis, were used. In experiment 2, eight non castrated pigs of 38 kg were used. It was confirmed that the ileal digestibility of DM, organic matter and energy decreased significantly (P < 0.05) with the inclusion of the foliage. However, there were no differences between the treatments with 0 and 10 % of the foliage, nor with 10 and 30 %. The rectal digestibility showed the same fact (P < 0.05) for the DM, organic matter and energy. The ileal and rectal digestibility, measured by difference, were 34.4 and 61.1% for the organic matter of the foliage, and 40.6 and 59.0 % for the energy. From the digestive point of view, the sweet potato foliage meal can be provided to pigs in levels not higher than 30 % of the food, as a source of proteins and minerals in diets of very low amount of fiber.

The in vivo and in situ rectal digestibility of sweet potato foliage meal was studied through mobile nylon bags. Four pigs of 40 kg were used, canulated in duodenum and fed maize/soybean diets, partially substituted with 0, 10, 20 and 30 % of sweet potato (Ipomoea batatas (L.) Lam) foliage meal, according to a Latin squeare design 4 x 4. There was no significant effect of the treatment on the in vivo rectal digestibility of sweat potato foliage in the pigs. The diet supplied only influenced significantly (P < 0.05) on the rectal digestibility of the OM measured in in situ. Coincidence was found in the rectal digestibility of the DM (49.4 and 50.2%), nitrogen (N) (44.7 and 45.4%) and the energy of sweet potato foliage (45.6 and 46.7%), when the nutritive value was measured in vivo and in situ. It is suggested that the nutritive values of sweet potato foliage diets can be determined in mouth-rectum of pigs by in vivo and in situ procedures differently, through the technique of mobile bag.

For studying productive and digestibility indices, 16 female and castrated male pigs in equal proportion from a commercial cross were distributed randomly in two groups. For six weeks, animals were fed ad libitum from 30 kg with high-test molassesor maize diets as the only energy source and torula yeast as the only protein source. Animals fed high-test molasses showed better performance (feed conversion, 4.59 and 3.45 kg DM/kg gain, P < 0.01) and rectal energy digestibility traits (83.7 and 88.1 %, P < 0.01) than those consuming maize. According to results obtained, growing pigs fed ad libitum high-test molasses diet as the only energy source can exhibit better performance traits than those receiving maize. Also, there are differences in rectal digestibility favoring the high-test molasses diet.

Chemical and physico-chemical characteristics were determined in 20 royal palm nut samples collected at random in northern municipalities (Bauta, Caimito and Guanajay) and from the south (Artemisa, Alquízar and San Antonio de los Baños) of the Cuban province of Artemisa during the summer of 2015. The nuts were from wild royal palms (Roystonea regia H.B.K. Cook) which were collected by pig producers raising pigs by agreement.It was found that the royal palm nut meal obtained after dried, fracturing and ground, contained on average 85.9% DM. There were no significant (P>0.05) effect between both geographical zones for ash, organic matter, crude fibre, NDF, ether extract and NFE with average values of 5.0, 94.9, 46.5, 57.7, 21.4 and 20.4% respectively. Crude protein concentration was different between zones (6.2 and 7.0%, respectively). Crude fibre and ether extract accounted for 40.4 and 36.9% of gross energy of royal palm nut meal (average, 22.8 kjoule/g DM). Density but water holding capacity, correlated (P<0.05) to fibrous fractions and ether extract. This ether extract was negatively correlated (P<0.01) to crude fibre concentration in the nuts. It was confirmed that royal palm nuts used in Artemisa for fattening pigs by agreement, are not different to that used for animal feeding in other Cuban provinces. Physico-chemical data being reported for the first time, allow predict voluntary feed intake in pigs fed on royal pam nuts. © 2016, Fundacion CIPAV. All rights reserved.

An experiment was carried out to determine the nutrients digestibility in Tithonia diversifolia foliage in fattening rabbits, 30 animals (1.450 g ± 93.77 initial body weight) were distributed according to a completely randomized experimental design in three treatments and ten replicates. The mash diets including 0, 9 and 18 % of tithonia foliage. The dry matter (DMD), organic matter (OMD), crude protein (CPD), neutral detergent fiber (FDND), hemicellulose (HEMD) and energy digestibilities (DE) were determined using the acid insoluble ash method. The nutrient digestibility in foliage was estimated by the replacing test ingredient method. The DMD, OMD, PCD and HEMD (51.12, 53.45 and 51.25; 51.99, 54.87 and 52.60; 68.57, 60.11 and 64.08, and 44.20, 45.37 and 47.24 % for the three foliage inclusion level, respectively) were similar (P>0.05) among diets. The foliage MSD, OMD, PCD, and ED DHEM was 53.80, 55.19, 59.17, 50.00 and 39.18%, while the protein and energy digestible content in tithonia foliage was 109.60 g/kg and 2139.45 kcal/kg. It was concluded that the tithonia foliage has high content of nutrients.

The indicators of pattern of feed intake were determinate in eight Cuban Creole and commercial pigs, feed with a commercial diet with addition or not of 20% of fruit of Roystonea regia. Replicated Latin square designs 2 x 2 with factorial arrangement were used. The factors evaluated were the diet and genotype. They were not significant interaction (P>0.05) between two factors evaluate. Significant effects of genotype and diet on the indicators measures were found. The inclusion of palmiche in the diet resulted in an extension of eating time (from 74.43 min to 102.75 (P<0.01)) and eating velocity lower (from 11.71 to 5.36 g/min (P<0.001)). Significant interdependence (P<0.01) between Water Holding Capacity (WHC) and the indicators of pattern of feed intake evaluate was not found. The Creole pigs not show superiority in from of commercial genotype. The inclusion of palmiche in the diets of pigs was considered.

A 2 x 2 factorial arrangement was used to determine the effect of sex (castrate males and female individuals) and body weight (32 and 47 kg) on rectal nutrient digestibility and feces output of 14 Mexican Cuino pigs fed ad libitum. A conventional diet was offered in meal form with an initial live weight of 20,1 kg. Contrary to what occurred for fecal N status, there was a significant (P <0,05) body weight x sex interaction for DM and organic matter rectal digestibility and for fresh, dry and water feces output. It was found that there was not significant (P >0,05) sex influence on DM, organic matter and N rectal digestibility of animals. There was not body weight effect on N digestibility. Feces output was not influenced by sex (P >0,05), but 32 kg pigs excreted significantly (P <0,01) more fresh material and water as well as N compounds and DM (P <0,001), than 47 kg animals. It is concluded that rectal digestibility of a conventional diet given ad libitum in meal form is high in the Mexican Cuino pigs.

Thirty two Yorkshire x Landrace x Duroc barrows of 61 days of age and 14 kg live weight were used. Animals were distributed according to a completely randomized design in four treatments, with 8 animals each, for studying the response of the animals to the inclusion in dry basis of 0, 5, 10 and 15 % of plantain (Musa spp) foliar residues meal in the feed. Meal was obtained by grinding the leaves and the upper first third of the pseudostem and later sun-dried. The variables initial live weight, final live weight, feed consumption, average daily gain and feed conversion, were recorded. There was no effect of the treatment at 87 d of age on final live weight (kg) and average dairy gain (g/d). Barrows fed diets containing plantain foliar residues meal did not reduce their feed consumption or undergo diarrhea. Feed conversion (kg DM/kg gain) was similar for all pigs (0 %, 2.63; 5 %, 3.00: 10 %, 2.91 and 15 %, 2.99). It is possible to include up to 15% of plantain foliar residues meal in the feeds for pre-fattening pigs.


To evaluate the effect of including different levels of Moringa oleífera leaf meal (0.10, 20%) in a starter feed, six castrated male pigs of a commercial crossbred of 20kg live weight were allocated to a double Latin square 3 × 3 design with three treatments. The apparent digestibilities of dry matter, organic matter, ash and nitrogen and the nitrogen balance were measured.The treatment which included 20% of Moringa leaf meal in the diet resulted in a significant decrease in digestibility of dry matter (DM), organic matter and crude protein, with respect to the rest of the treatments. Excretion of N in feces and urine increased and N retention decreased with increasing level of Moringa leaf meal in the diet. The results suggest that it is possible to include up to 10% of Moringa oleífera leaf meal in the diet of growing-fattening pigs without affecting digestive performance. © 2014, Fundacion CIPAV.
