Diet selection by Awassi lambs fed individually in a cafeteria feeding system

Abstract This study was designed to monitor Awassi lambs in a cafeteria feeding system with respect to diet selection and growth in comparison to conventional feeding. Sixteen, 3-month-old male lambs were used and kept individually for 70 days. The main effect was the feeding system (cafeteria and control or conventional). Cafeteria lambs (n=8) were offered the main ingredients (barley, cotton seed meal (CSM), wheat bran and alfalfa straw), while control animals (n=8) were fed a single diet containing 10.3 MJ ME, 161 g crude protein, 95 g crude fiber kg−1 with the same ingredients. Cafeteria animals preferred a lower caloric (10.1 MJ ME kg−1), but a higher nitrogenous (178 g CP kg−1) and fibrous (98 g CF kg−1) diet than control animals (P 0.05). Cafeteria lambs can eat a maximal amount of 446 g CSM or 560 g barley kg−1 according to their stage of growth or fattening. Lambs were different with respect to diet selection patterns. In conclusion, lambs can consume a diet matching their presumed nutritional requirements from feed ingredients and determine their priorities for protein and energy in response to growth and fattening without changing their performance in comparison to single-fed lambs.

Changes in Gross Chemical Compositions of Ewe and Goat Colostrum During Ten Days Postpartum

Abstract Keskin, M., Güler, Z., Gül, S. and Biçer, O. 2007. Changes in gross chemical compositions of ewe and goat colostrum during ten days postpartum. J. Appl. Anim. Res., 32: 25–28. This study was carried out to determine the exact ‘Colostrum producing period’ in Awassi ewes and Shami (Damascus) goats in Hatay province of Turkiye based on changes in gross composition of milk during 10 days post partum. Goats produced high crude protein and fat milk for 3–5 days post partum. Whereas, in ewes it was 3 days. Ewes colostrum was richer in respect to total solids (TS), crude protein (CP), fat, lactose and ash as compared to goats colostrum. It is recommended that first three days milk (colostrum) must be fed to kids/lambs for maximum benefits.

Reproductive characteristics of Awassi ewes under Cornell alternate month accelerated lambing system

We investigated the reproductive responses of Awassi ewes under Cornell alternate month accelerated lambing (CAMAL) system. Ewes were randomly allocated to two experimental groups. The first group (control group) consisted of 20 ewes exposed to rams in September under conventional management system, while the second group (CAMAL) was divided into four sub-flocks containing each 20 ewes exposed to rams to obtain three lambing in two years with different breeding and lambing months. In CAMAL ewes, oestrus was synchronized using intra-vaginal sponges with progesterone and Pregnant Mare Serum Gonadotropin (PMSG) administration. The results obtained revealed that within CAMAL group, the percentage of animals in heat, onset of oestrus, litter size, birth weight and weaning weight were affected by mating months. September and November were the most appropriate months for oestrus ratio (97.5%) and litter size (1.18 and 0.98, respectively). Lambs of control group were heavier at birth and weaning than those of CAMAL group. On the other hand lamb yield was not affected statistically by the CAMAL administration.

Effects of supplemental feeding on performance of Kilis goats kept on pasture condition

Abstract In this study, the effects of supplemental feeding to extensive pasture condition on some reproductive and milk yield characteristics in Kilis goats have been investigated. For this study, 180 Kilis goats were used. These goats were assigned into two groups as control and treatment. Control goats were allowed to graze pasture, while treatment goats were additionally fed 750 g/day with concentrated feed per head plus pasture facility. At the end of the study the average fertility rate, marketable milk yield, lactation length and lactation milk yield were determined as 115.56%, 215.5 ± 5.28 l, 212.5 ± 1.09 days 293.7 ± 5.76 l, respectively, in the control goats; 131.1%, 304.1 ± 6.48 l, 256.5 ± 1.79 days, 408.3 ± 7.21 l, respectively, in the treatment goats. To conclude, supplementary feeding plus pasture improved reproductive and milk yield performance in Kilis goats.

Applicability of different Synchronization Protocols during Breeding Season in Kilis Goats

Article No.: 052616099 DOI: 10.15580/GJAS.2016.6.052616099 The objective of this study was to determine the effects of four different oestrus synchronization protocols on some reproductive characteristics in Kilis goats. For this purpose, 75 heads of goats were used and divided into 5 groups as Progesterone (P4: intravaginal sponges with 20 mg progesterone), Progesterone + Pregnant Mare Gonadotropin Hormone (P4+PMSG: intravaginal sponges + 300 IU intramuscular injection of pregnant mare serum), single dose Prostaglandin F2 Alpha (PgF2α-I: single PgF2α intramuscular injection), double dose Prostaglandin F2 Alpha (PgF2α-II: double PgF2α intramuscular injection) with 11-days interval and Male Effect (Control). All goats were naturally mated. At the end of the study, kidding rates of single and multiple birth types were calculated as 33.34 %, 66.66 % in P4; 40.00 %, 60.00 % in P4+PMSG; 46.67 %, 53.33 % in PgF2α-I; 46.67 %,53.33 % in PgF2α-II and 53.33 %, 46.67 % in control groups, respectively. Inconclusion, it was detected that P4+PMSG application increased kids number. Submitted: 26/05/2016 Accepted: 03/06/2016 Published: 25/06/2016
